Replace the VMSTOP macros with a proper state type
Today, when notifying a VM state change with vm_state_notify(),we pass a VMSTOP macro as the 'reason' argument. This is not idealbecause the VMSTOP macros tell why qemu stopped and not exactlywhat the current VM state is....
Drop the vm_running global variable
Use runstate_is_running() instead, which is introduced by this commit.

xen: use uint64_t instead of target_ulong in cpu_ioreq_move
cpu_ioreq_move might move 8 bytes at a time so we must make sure thatthe temporary variable can hold 8 bytes.

xen: Fix the memory registration to reflect of what is done by Xen.
A Xen guest memory is allocated by libxc. But this memory is notallocated continuously, instead, it leaves the VGA IO memory space notallocated, same for the MMIO space (at HVM_BELOW_4G_MMIO_START of size...
cpu-common: Have a ram_addr_t of uint64 with Xen.
In Xen case, memory can be bigger than the host memory. that mean a32bits host (and QEMU) should be able to handle a RAM address of 64bits.

xen: introduce xen_change_state_handler
Remove the call to xenstore_record_dm_state from xen_main_loop_preparethat is HVM specific.Add a new vm_change_state_handler shared between xen_pv and xen_hvmmachines to record the VM state to xenstore.

notifier: Pass data argument to callback
This allows to pass additional information to the notifier callbackwhich is useful if sender and receiver do not share any other distinctdata structure.

xen: Introduce the Xen mapcache
On IA32 host or IA32 PAE host, at present, generally, we can't createan HVM guest with more than 2G memory, because generally it's almostimpossible for Qemu to find a large enough and consecutive virtualaddress space to map an HVM guest's whole physical address space....
